Step 8 In the Authentication Timeout Value field, enter the amount of time (in seconds) before a LEAP
authentication attempt is considered to be failed and an error message appears.

Step 9 Click OK to exit the LEAP Settings screen.
Step 10 Check the Allow Fast Roaming (CCKM) check box on the Network Security screen if you want to
enable fast roaming for your client adapter.
• Checking this check box enables the client adapter to use CCKM when associated to an access point
that uses CCKM or to associate to access points that are not using CCKM.
• Unchecking this check box prevents the client adapter from using CCKM even with access points
that use it.
Default: Unchecked
Note Refer to the “Fast Roaming (CCKM)” section on page 5-28 for additional information.
Step 11 Check the Allow Association to both WPA and non-WPA authenticators check box if you want to
allow the client adapter to associate to access points that are configured for LEAP authentication with:
• WPA enabled (associates with WPA security)
• WPA disabled or not supported (associates without WPA security)
• Cisco migration mode, where WPA is optional (associates without WPA security)
If this check box is not checked, the client adapter can associate only to access points that are configured
for LEAP authentication with WPA.
Default: Unchecked
Note This parameter is available only if you enable WPA.
Step 12 Click OK to exit the Network Security screen and return to the Profile Manager screen. On the Profile
